Abstract

In this paper, call setup time in Session Initiation Protocol (SIP)-based videotelephony is analyzed. We used a 3G network emulator to measure post-dialing delay, answer-signal delay and call-release delay. The results are compared to local, national, international and overseas intranet LAN calls. Furthermore, we have also studied the effect SIP calls over lossy channels with restricted bandwidth, typical of mobile network signaling bearers.

3G网络中的SIP呼叫设置延迟

本文分析了基于会话发起协议(SIP)的可视电话的呼叫建立时间。我们使用3G网络仿真器测量拨号后延迟、应答信号延迟和呼叫释放延迟。结果与本地、国内、国际和海外局域网呼叫进行了比较。此外，我们还研究了在带宽受限的有损信道(典型的移动网络信令承载)上的SIP呼叫的影响。
